The beta, which was originally scheduled for a December release will now take place in “early 2016” while an Xbox One pre-order exclusive alpha testing phase will be conducted between December 9th - 12th.

Players participating in the alpha will be forced to sign a non-disclosure agreement promising that they will not record game footage, take snapshots of the game, or discuss the game anywhere but the exclusive developer forums. 

Head’s up: the alpha is a hefty file, clocking in at 23.2 GB. Make sure the space is cleared on your Xbox One before attempting a download. 

Despite the new alpha testing stage and the beta being pushed into 2016, The Division’s release date remains unmoved. The game will be released on March 8th, 2016 unless some game breaking bug is revealed in the testing.
